The friends are playing a game of "truth or dare," but Alecia thinks the dares are too tame. She challenges Niki to call up the new boy Ryan. Niki gets his answering machine and leaves a message for him to call her. Then Alecia dares (Cris) Castelli to take them all for a ride in her father's beloved vintage '65 Mustang. The girls go to the Castelli's pizza restaurant where they distract Cris' dad while she gets the keys to the car. While out riding in the car, Cris had difficulty shifting and when Alecia tries to help, they strip the car's clutch plate.

Cris' brother Steve comes out to help but the car will need a specially-ordered part. Castelli has the car towed back home and plans not to tell her father, but to get the part and have it replaced without his knowing. Meanwhile, she and Alecia have a falling out when Cris blames Alecia's dare for causing the whole problem in the first place. Niki is getting frantic because Ryan hasn't returned her call. Back at the restaurant Dad says he and Steve are going to a Mustang rally in a couple of days. Cris tries to make up reasons why her father shouldn't to go to the rally, saying that it is "unsafe" somehow, but he's unconvinced. Later when the girls are together, Castelli decides she must tell her father what she has done. Sierra then confesses to Niki that Ryan has failed to call back because she told him Niki's call was a joke. Sierra admits that she wanted to go out with the guy herself. Rather than being mad at Sierra, Niki is relieved that she hasn't "lost it."

While Cris is telling her father the truth about the car, Alecia comes in and takes the blame also. Mr. Castelli had figured out what happened, but he let the girls squirm a little because they didn't tell the truth. Castelli and Alecia receive punishments for their actions, but their friendship is back on track.
